This is all five comics in the What If? Series by Marvel (officially, volume 7) and fills a request from KAT. The stories included are:

-What If House of M - What if the Scarlet Witch had said 'No More Powers' instead of 'No More Mutants'?
-What If Fallen Son: The Death of Captain America - What if Iron Man had been killed instead of Captain America?
-What If Newer Fantastic Four - What if the New Fantastic Four had battled Thanos?
-What If Spider-Man: Back in Black - What if Mary Jane had been shot instead of Aunt May?
-What If Secret Wars - What if Doctor Doom had kept the Beyonder's power?

Four of the books are in nice-looking Minutemen scans; House of M is also a good one, by SEGoat-DCP. Full titles for the scanner groups are in the individual comic names. Thanks to all of them for their efforts; please seed, and enjoy! :-)
